Abstract
We examined by light and electron microscopy 99 vascular lesions removed on 17 occasions over a 2-year period from a 55-year-old black man. The lesions all showed histologic features of a vascular neoplasm composed of enlarged “histiocytoid” endothelial cells and overlapping features of angiolymphoid hyperplasia with cosinophilia and Kaposi's sarcoma. An apparently unique feature was early loss of melanin from the overlying cpidermis and a monocuclear inflamatory-cell infiltrate. The patient also had an abnormal immunologic state very similar to that seen in homosexuals with Kaposi's sarcoma.Keywords
